I've a number of different species of plecs that have been happily sharing a tank now for the best part of a year now. I introduced a 2" blue phantom to the tank 5 days ago (Saturday). Silly mistake but after moving furniture but I forgot to plug the heater back in for 24 hours from Sunday night to the Monday night. Monday night all the plecs were out in the open on top of the rocks and not underneath them as they normally are. Was this down to the drop in temperature? The green phantom was stuck on the glass relatively near the surface alongside the newly introduced blue which had been displaying this behaviour since its introduction. That Monday night the heater was back on and I did my weekly 20% water change (50/50 RO/Cond. tap water). Changed filter wool, carbon granules and added normal amount of bacteria balls and did a 2 week filter head clean through.
Tuesday morning temperature back to normal but Tuesday night green phantom 4" was dead. Colombian snowball & King Tiger plecs were constantly fanning themselves on rocks and still up on the glass was the blue (not normal daytime behaviour in my tank).
Water litmus tested and all parameters okay. Decided on a 50% water change out of part caution and part desperation on the Wednesday night.
Thursday night blue phantom pleco is dead. Water test all parameters okay. Para pleco is now up on the glass along with snowball and king tiger still displaying what seem to be heavy breathing problems particularly the king tiger.
Has the blue bought in something? Any ideas and what can I do, I'm worried more will go in the days to come. Please help with any advice.
